MAlNSPRlNG-WlN DER FOR WATCH-MAKERS.

SPECIFICATION forming part ofiLetters Patent No. 349,291, datedSeptember 14, 1886. Application filed December 26, 1885. Serial No.186,776. (ModelJ To aZZ whom it may concern:

Be it known that I, PETER ZIEGEL, of Nash ville, in the county of\Vashington and State of Illinois, have invented a certain new anduseful Improvement in Mainspring-\Vinders for Watches, of which thefollowing is a full, clear, and exact description, reference being hadto the accompanying drawings, forming part of this specification, .andin which Figure 1 is a side elevation of the instrument, showing thespring holding pins retracted. Fig. 2 is atop view of the instrument asshown in Fig. 1. Fig. 3 is a side'elevation of the in strument .with thepins projecting from the face of the volute cam. Fig. 4 is a top view ofthe instrument as shown in Fig. 3. Fig. 5 is a front elevation. Fig. 6is a section at 6 6, Fig. 7. Fig. 7 is a section at 7 7, Fig. 5; andFig. 8 is a side view-of the rail guide, plate, or disk within thevolute cam or head.

My invention relates to devices for winding the mainspring of watches,aiulinserting them in the barrels of the same, with a novel arrangementof adjustable gage pins that are regulated to the diameter of the barrelthat holds the spring; and my invention consists in features of noveltyhereinafter fully described,

Referring to the drawings, in which similar lettersillustrate like partsin the several figures, A. represents the pedestal of the instrument,and A the foot of the pedestal intended to be gripped in the jaws of avise.

B designates the sleeve of the winder, which is provided at one end witha volute cam or head, G, having a radial guide plate or disk, D, hidwithin it. (See Fig. 8.) There are divergent slots D in this disk,through which d in a similar guide plate or disk, d, as seen in Fig. 6,the slots in both plates coinciding with each other. The face of theVolute head is formed of a rotary disk provided with curved or voluteslots O", through which the aforesaid gage-pins also pass, and it willbe seen that as this face is turned round the curved slots eX- pand orcontract the area of the gage as desired, regulating it to the diameterof the barrel F that is to hold the spring G. The shaft H passes throughthe sleeve, and has longitudihold and con fine the spring.

nal motion sufficient to allow its end I to project through the face ofthe volute head. A pin, J, near the end of the shaft engages in the slotin the inner end of the mainspring.

K is the crank of the shaft, which, with its handle K, winds the spring.

' L is a pivoted cam-lever, which forces out the disk-frame that holdsthe gage-pins, thereby projecting them through the volute head to Thesepins are beveled on the outside of their points to allow an easypresentation of the barrel over them, and are recessed or half cut awayon the inside to allow astraight backing for the mainspring, which iswound within them, and for which there is thus provided a recessed seatwith a shoulder formed by the cut-away in the pin.

The operation of the winder is as follows: The instrument is placed inthe vise, and the cam-lever brought to bear against the rear disk of theframe carrying the gage-pins, which are by that meanspushed forwardthrough the volute camhead until they project sufficiently to clasp themainspring as it is wound. The facedisk of the head, which is providedwith volute slots that regulate the position of the gage-pins, is thenturned round, and the curved slots are thus made to either expand orcontract the area embraced by the gage-pins,regulating them to thediameter of the barrel. The shaft is then moved longitudinally forwarduntil its end projects beyond the face-disk sufficiently to attach theslotted inner end of the spring to the pin near the end of the shaft.The crank is then made to turn the shaft until the spring is woundtightly against it. The barrel is next placed over the gage-pins, withinwhich the spring is embraced, and the cam-lever being turned back torelease its hold, the disk with the accompanying gage-pins are readilywithdrawn, leaving the mainspring in the barrel.

It will be seen that by the novel device of the volute cam or head withits accompanying slotted disks and gage-pins one instrument may beregulated to conform to watch-barrels of any dimensions, the changebeing made in a few seconds without removal from the vise.

When it is considered that many barrels of varying diameter are beingfilled at the same bench and by the same mechanic, it is an evidentfeature ofgrea-t practical advantage to be able to effect the workwithout a change of instiruments.

I claim as 1nyinventi0n 1.
